In their search for generalizable behavioral patterns and design principles, cognitive field researchers should reflect on the epistemological limitations of empirical studies. In this paper we describe a framework for epistemological analysis that can help serve this purpose and discuss its application to two prototypical cases of cognitive engineering research: laboratory experiments and fiel...

Abstract To address the problem of low accuracy fault information extracted from motor-bearing vibration signals, a feature extraction method based on Whale Optimization Algorithm (WOA)-Variable Modal Decomposition (VMD) energy entropy is proposed, and modified WOA-Support Vector Machine (SVM) used for diagnosis. Firstly, optimal number modes K penalty parameters α variable modal decomposition ...

A Real-time electricity market transaction is an important method that used to realize the interactive balance of source-network-load in a new generation power system. Based on multi-camp economic choice and needs national conditions, emergence cluster operators inevitable. Due stability development photovoltaic users, it evaluate importance users user group. In existing model, are too sensitiv...

The objective of this paper is to review the use thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques as research tools in luminescence, particularly detect presence trapping centers that can degrade efficiency scintillators, shape properties persistent phosphors, storage phosphors dosimeters. A brief main analysis provided, followed by a discussion their limitations. ...
